Pulmonary infection with Petriellidium boydii.

A 52-year-old woman with pulmonary involvement with Petriellidium boydii in a bronchiectatic lung segment is described. Pulmonary involvement with this organism has been most frequently described in patients with underlying systemic diseases or compromised immune systems. This patient apparently had neither problem and was normal in all other aspects. Surgical resection was done to avoid local pulmonary parenchymal invasion or dissemination of this fungus. The patient is now in good health two years after operation.
